Also be provided with router three 4 and set-top box 32 among Fig. 2: the two can be couple to control desk element 20.In specific example, router three 4 can be that the home wireless router that is connected that provides with network 30 is provided.Perhaps, router three 4 network that can utilize simple Ethernet cable to be provided for the transfer of data that is associated with system 10 is connected.Hand-held set 28 can be by by seat charger 26(as shown in Figure 2) charge.[hand-held set 28 can work when docking.] or, hand-held set 28 can be powered by battery, solar recharging, cable or the combination by any power source or these machine-processed any appropriate.
In a specific example, the call signaling of system 10 can provide by Session Initiation Protocol.In addition, the medium that are used for videoconferencing platform can provide by Security Real Time Protocol (SRTP) or any other suitable real-time protocol (RTP).SRTP has solved the safety problem of RTP, and can be configured to Real-time Transport Protocol is increased confidentiality, message authentication and playback protection.SRTP is preferred for protection ip voice (VoIP) flow, and this is because it can be used in conjunction with header suppression, and in addition, it is usually to not influence of IP service quality (QoS).Pass through for Network address translators (NAT)/fire compartment wall (FW), any suitable mechanism can be used by system 10.In a specific example, these functions can be passed through application program (STUN) and provide with the interactive fractionation tunnelling VPN that is connected foundation (ICE) by having the session that is used for NAT.
Signaling can propagate into Call Agent via VPN.In addition, medium can be directly send to another end points (promptly from a videoconferencing platform to another videoconferencing platform) from an end points.Notice that employed term " medium " comprises voice data (can comprise speech data) and video data (view data that can comprise any kind) here.Video data can comprise any suitable image (for example by camera components 14, by counterparty's camera components, by camera, the image of catching by smart phone, by iPad etc.).Here employed term " smart phone " comprises the mobile device of any kind that can cooperate Video service and work.This comprises naturally such as products such as Google Droid, iPhone, iPad.In addition, term " signaling data " comprises any suitable control information that can send towards network.This can comprise the negotiation that is used to set up the flow of video session at first and may be suitable for any type of particular video conference (for example at bit rate, at bandwidth etc.).Project such as flow of management flow, account's flow (being used for nusrmgr.cpl, contacts list [comprise buddy list, will describe in detail below] etc.) and/or other type and so on that provides as the part of media data can also be provided not for this.
In order to tackle symmetrical NAT, in a particular embodiment, use the relaying NAT(TURN that passes through) can be used by system 10.In specific example, the user name that is used for videoconferencing platform can be provided by number E.164.Perhaps, user name can be simple user ID(for example by service provider's appointment, by the user select etc.), user's full name (perhaps group name), head portrait or can be used for any other symbol, numeral or monogram that a user and another user are differentiated.Notice that single name also can be associated with group (for example family, commercial unit etc.).The fail safe of the communication of system 10 can solve with a variety of modes.In one implementation, Video service (that is cloud service) can be protected by any suitable security protocol (for example security software, adaptive security facility (ASA) etc.).In addition, intrusion protection system, fire compartment wall, anti-denial of service mechanism can be provided for this architecture (all inside and outside the network and/or in residential environment this locality).
Then consider the details be associated with the infrastructure of system 10, in a specific example, camera components 14 be configured to catch, write down, the video camera of maintenance, buffer memory, reception and/or transmission view data.This can comprise by network 30 grouping is sent to suitable next destination.The view data of catching/writing down can be stored in the camera components 14 itself, perhaps provides in certain suitable storage region (for example database, server, control desk element 20 etc.).In a particular instance, camera components 14 can be its oneself network equipment and have independent IP address independently.Camera components 14 can comprise wireless camera, high definition camera or be configured to catch any other suitable camera apparatus of view data.
In some examples, control desk element 20 within it portion be provided with optical sensor independently and give the daylighting of booking room to measure.Subsequently, this architecture can be regulated camera exposure, shutter, lens adjustment etc. based on detected light in the room.Camera components 14 also attempts to provide this function; But having independently optical sensor provides based on the light that senses in the room and has regulated the deterministic mode of having more of these parameters.A kind of algorithm (for example in camera components 14 and/or control desk element 20) can be performed to detect based on light and carry out camera adjustments.Under idle (IDLE) pattern, the camera lens of camera components 14 can be closed automatically.The camera lens of camera components 14 can be opened for incoming call, and can close (perhaps these operations can be controlled by hand-held set 28) when calling is finished.This architecture also can be tackled the challenging daylighting environment at camera components 14.For example, have behind under the situation of bright daylight a people, system 10 can optimize the exposure to this human face.
About voice data (comprising speech data), in a specific example, loud speaker 16 is provided as microphone array, and this array can suitably be calibrated.Notice that in some consumer used, this consumer's home system was a variant, these most of business systems with the office structure with fixing (measurable) form contrast.In specific example, camera components 14 can include the array of 8 microphones, but as an alternative, the microphone of arbitrary number can be provided to suitably capturing audio data.These microphones can be placed to realize desirable audio capturing function at interval by linearity or logarithm.In some implementation, MEMS (micro electro mechanical system) (MEMS) technology can be used to each microphone.The MEMS microphone is represented the distortion of Electret Condencer Microphone design, has built-in analog to digital converter (ADC) circuit.
The audio frequency mechanism of system 10 can be configured to system is added delay to guarantee that acoustic apparatus can correctly work.In fact, this video conference architecture itself is owing to suitable delay is not known in unique field of consumer.For example, may there be the household audio and video system that is used to the acoustics purpose.Thereby system 10 can determine for this specific environment it will will be unique suitable delay.In a particular instance, this delay can be measured, wherein suitably offset from the Echo of existing loud speaker.The watermark embedder stamped signature also may be provided in each loud speaker, and wherein this stamped signature can be detected to determine suitable delay.Note, also have certain additional delay of self adding, because clock mechanism is not deterministic usually by display 12.This architecture can dynamically be upgraded this delay to tackle this problem.A lot of functions in these functions can be finished by control desk element 20 and/or camera components 14: the two can be used to carry out these functions by configuration intelligently and regulate.
This architecture can also be sent signal (for example white noise) as the test that is used to measure delay.In some instances, this function is finished automatically, and does not need to point out the user.This architecture can also be utilized wireless microphone 24, and in some implementation, this wireless microphone 24 can use dedicated link.Wireless microphone 24 can be by pairing (being similar to Bluetooth pairing) so that privacy concern can suitably be solved.Wireless microphone 24 can be brought to Anywhere (for example in the room, in the room etc.) and suitable audio-frequency function still is provided, and the wherein multiplexed control desk element 20 that will occur in is sentenced and is used for this application-specific.Similarly, also can there be same situation (perhaps loud speaker/microphone can be provided as portable mobile unit together) for given loud speaker.This loud speaker can be used in the room similarly, in the room etc. Anywhere.It should be noted that this is not only problem easily, and suitably to catch/transmitting aspect the audio signal with suitable intensity and quality also be performance issue.
With regard to call answering and video messaging, hand-held set 28 allows the individual to have the option of accepting audio call but not replying conference call.This is because hand-held set 28 may have the intelligence of coming work purely as mobile phone.Therefore, hand-held set 28 can be provided with the application that is used for the control of video meetings and activities on the described smart phone easily with various types of smart phone replacement/replacements.Hand-held set 28 is also supported the ability of (by hand-held set itself) notified incoming call conference call, has described calling is presented on option on the display 12.Can use simple visual alarm (for example LED, vibration etc.) to come instruction video message waiting for is listened to/is watched.
Video messaging can comprise and will indicate the snapshot of the frame of video of real messages image.In user's video inbox, current video-mail can comprise the image of the real messages that is stored for the playback in future.For example, message is from mother of user, and then video-mail will be included in a series of snapshots of mother's speech during this video-mail.In a specific example, the practical video mail is sampled with certain hour interval (for example every 10 seconds) to generate these images, and these images are as the preview of video mail messages.Perhaps, impinge upon soon on the number and can be limited.In other example, snapshot is selected arbitrarily or is selected in beginning, centre and ending place of video messaging.In other implementation, snapshot is used as the percentage (for example in 20% mark, in 40% mark with in 100% mark) of whole video message and takes.In other example, the video-mail in the inbox is by only showing the image that is associated with the specific user ID that writes video messaging and by preview.
In the operation of the user's who relates to the normal tv program of watching on the display 12 example, incoming call can be received by videoconferencing platform.Even television set is closed, notice also can arrive (loud speaker that for example passes through system 10).If someone selects to reply this calling, then videoconferencing platform is taken over television set.In relating to an example of digital video recorder (DVR), program may be suspended.In other example, the user can keep minimizing with calling out, and makes (for example) user to talk with friend when watching football match.Control desk element 20 can be configured to recording messages, then this message is sent to any suitable next destination.For example, the user can send link to the someone at particular message.The user can also use Flip Share or YouTube technology to upload/send a message to any suitable destination.On ordinary meaning, even message can be arranged in network cloud the power supply at dwelling house place break or the user not at the dwelling house place, message still can accessed (for example passing through Radio Link).
The user can also switch to hand-held set 28 from video calling, and switches back video calling from hand-held set 28.For example, the user can make a call on smart phone, transfers the call to video conference displays 12 subsequently.The user also can do conversely, and promptly the user starts from videoconferencing platform and switches to smart phone again.Notice that wireless microphone 24 can be operated in the specific preferable range (for example 12 to 15 feet), if the wherein individual place that moves to away from described scope, then the user can select to transfer to hand-held set 28(by more traditional liaison mode).Consider following situation: owing to the kinsfolk makes the room become noisy, and the user on the conference call selects to switch to simply smart phone, arrives given base etc.
Motion detection also can be used to initiate or to reply video call.For example, be difficult in the living room find under the situation of remote controllers, can using the posture of simply waving to reply the video call of incoming call.In addition, system's (for example camera components 14 and 20 cooperations of control desk element) can detect specific body part usually to carry out this agreement.For example, this architecture can be run display 12 and be used to reply between the waving of incoming call and be distinguished dog.Along similar circuit, the user can use different postures to carry out different call function (hand of for example holding him is to place conversation wait state, to clap hands to finish conversation, to give directions the someone is added contacts list etc.).
Notice that Wi-Fi is supported fully by system 10.In most of video conference scenes, may have mass data (in these data many) biography and advance (or spreading out of) this architecture the time requirement strictness.Connecting the video packets of propagating (being low-latency data) by Wi-Fi can correctly be admitted by system 10.In a specific example, do not move the background image of (static state) and can from video image, be told, described video image is being shown device 12 and is presenting.Then, this architecture (for example by control desk element 20) can reduce the bit rate on those images significantly.Then, can other image that moves (promptly changing in some way) be distributed.In some exemplary implementation, face detection algorithm also can be used, and wherein video is based on the result of those algorithms and optimised.
The mechanism that some telephony feature allows hand-held set 28 speed dialling to be provided and to be used for the contact person is deposited in contacts list.Can call out the user on speed dialing list or contacts list by the single button press on the hand-held set 28.In addition, can utilize the UI of hand-held set 28 or the UI18 on the screen to make a call.In addition, calling can be initiated from the web door, and the caller can come to initiate in the affirmation calling of end points place by voice special use or the video call button of pushing on the hand-held set 28 in this case.In addition, calling can be initiated (for example calling out this person by the Facebook object of clicking the someone) from other web page via the calling instrument.In addition, the caller can record in online communication in (address list that for example is stored in all the Telepresence users in the database) and search the recipient, and this recipient is made calling, and recipient's contact details are deposited in the contacts list.With regard to the receiver, video Conference Calling, incoming call can utilize the single button press on the hand-held set 28 and be accepted.Calling receiver has an opportunity to receive or refusal is called out.Unaccepted calling can be routed to video-mail (if the security set of the side of being received allows).
About speech quality, if available bandwidth reduces during conversing, then video resolution suitably is lowered.If available bandwidth increases during conversing, then video resolution can be enhanced.Can on display 12, provide icon on the screen to inform the quality that its video conference of user is experienced.The purpose of this information can be for the poor quality experience of informing that user's possibility causes owing to network condition, and the user can improve its experience by its broadband service of upgrading.When utilizing camera when communication, the picture on the display 12 can be by frame in black surround: no matter the actual mass of camera video how.
About video-mail, when calling can not be replied in real time, this calling was not lost, but is automatically forwarded to video-mail.Video-mail can be from employed any other the suitable endpoint device of video conferencing system, web door, smart phone, laptop computer or user and is accessed.Notice that the user has been provided the video-mail inbox that for when calling party will be transferred to the user fixed time ability at interval is set.Term " fixed time at interval " comprises number of times, regular hour section (for example in several seconds) or zero interval of jingle bell, and under the situation at zero interval, the video call request of calling party will be routed to user's video-mail immediately.In certain embodiments, " fixed time interval " has the default value by administrator configurations.
In the specific implementation mode of system 10, video-mail can be stored in (for example in the cloud) in the network.Perhaps, video-mail can be stored locally on consumer's dwelling house place (for example being stored in laptop computer, personal computer, external fixed disk drive, server place or any other suitable data storage device).Video-mail can be gathered with the playback control of following minimum and plays: play, suspend, stop, F.F. or jump into, rewind down or jumping move back, turn back to beginning.In the specific implementation mode, video-mail is only checked by desirable recipient.Notice to the new video mail can be sent to miscellaneous equipment by Short Message Service (SMS) text message (for example sending to mobile device) or by Email.Also can on hand-held set 28, show instant notice.For videograph, video can be recorded and be stored on the network for checking in the future and distributing (for example as the part of Video service, this will be described in detail with reference to figure 3 below).Calling can be similarly by real time record and be stored in the network for checking in the future and distributing.When sharing the video that is write down with the video conference user, this system result can specify concrete which video conference user that the access right of pair video data is arranged.When sharing tabulation and comprise one or more e-mail address, in the specific implementation mode, access control is not activated (for example the individual of any URL of having can accessing video).
With regard to medium were shared, system 10 can be provided for utilizing removable flash media, flash memory and hard disk drive high definition digital video camera, digital camera and other portable memory apparatus to share the simple mechanisms of digital photos and video.This can realize that described USB port can be located at control desk element 20, display 12, camera components 14, special equipment place or any other suitable position by supporting these equipment to be connected with the external USB of USB port.

Note,, understand that data problem to occur in a lot of Video Applications be very important for the purpose of some example technique of illustrative system 100.Video processing unit can be configured to skip during to video sequence coding the macro block of vision signal.This means for these macro blocks and will not transmit data behind the coding.This may comprise codec (for example MPEG-4, H.263 wait), and for codec, bandwidth and network congestion are to need very much the problem considered.In addition, for mobile video telephone and for the computer based meeting, it is very precious handling resource.This comprises that personal computer (PC) uses and be used for the more strong system of video conference (for example Telepresence).
Coding efficiency is subjected to the restriction of computational complexity usually.Computational complexity can be contemplated to by the macro block at video data not to be handled these macro blocks (for example coding before) and is reduced in the time of will be skipped.Skip macroblock has been saved sizable computational resource, because the subsequent treatment (for example estimation, conversion and quantification, entropy coding etc.) of macro block can be avoided.Some software videos are used by abandoning the utilance that frame comes processor controls at coding between active stage: cause the unexpected motion in the decoded video sequence usually.Distortion also is very general when skipping by optionally (or improperly) when macro block.It is very important reducing computation complexity and managing bandwidth and transmitting vision signal enough for the participant spectators (i.e. not significantly deterioration, distortion etc. of this vision signal) simultaneously.
According to instruction of the present disclosure, system 100 adopts senior coding (ASC) method of skipping that effectively addresses the above problem.Particularly, this agreement can comprise three significant components, these three assembly problems that settling time, video noise was presented together.The first, system 100 variation statistics of frame the preceding on the time of expression efficiently.The second, system 100 can discern the value that the most probable of each picture element " can be skipped ".The 3rd, in conjunction with being provided with reference base picture, system 100 can determine whether picture element should be encoded as behind the current coding and skip.In these assemblies each will further go through below.

In a kind of exemplary implementation, video processing unit 117,127 comprises the software (for example as the corresponding senior part of skipping coding module 136a-b and video encoder 134a-b or facial optimized encoding module 135 shown in Fig. 6) that is used to realize intelligent video enhancing operation, as summarizing in this document.In other embodiments, this feature can be provided beyond any element in said elements, perhaps is included in certain other video element or the end points (any one in this video element or the end points may be special-purpose) to realize this desired function that has.Perhaps, several elements can comprise the software (perhaps reciprocating type software) that can coordinate to realize described operation, as summarizing here.In other embodiments, any apparatus among the shown figure can comprise and auxiliaryly realizes that these skip any suitable algorithm, hardware, software, assembly, module, interface or the object of encode management operation.

Forward Fig. 6 to, Fig. 6 is the simplified block diagram that illustrates according to the example data flow in single endpoint of an embodiment of the present disclosure.In this specific implementation mode, camera components 116 and video processing unit 117 are illustrated.Video processing unit 117 comprise change that test 142, threshold value determine 144, histogram upgrades 146, benchmark registration 148 and benchmark 150.Video processing unit 117 can also comprise aforementioned video encoder 134a, senior coding module 136a and the facial optimized encoding module 135 skipped.Notice that the dotted line of Fig. 6 is represented optionally thereby the path that can be skipped.
With regard to operation, camera components 116 can be caught the input video that is associated with participant 119.These data can flow to video processing unit 117 from camera components 116.Data flow can be directed to this encoder of video encoder 134a(can comprise the senior coding module 136a that skips), and be sent to threshold value subsequently and determine 144 and change test 142.Data can be used as a series of still images or frame and analyzed, and these still images or frame be displacement in time each other.These images are determined 144 and change test 142 and analyze by threshold value, will describe in detail below.
With reference now to Fig. 7,, Fig. 7 shows the multistage histogrammic reduced graph according to an embodiment of the present disclosure.This specific activities can occur in threshold value and determine 144 and change in the test 142.In this embodiment, data are analyzed to represent the variation statistics of per two successive frames with multistage histogrammic form.Should be noted that this notion is based on following intrinsic cognition: typical video conference scene (for example Telepresence scene) can frequently and/or significantly not change.Each histogram can write down the variation statistics of a picture element (being video image).Picture element can be considered to a pixel in the original image or reduce the image of resolution (dwindling).In this specific example, pixel can be combined with the macro block of formation image, and image can be grouped into 16 * 16 macro block lattice.Other block form also can easily be used, and wherein the configuration of these packet modes or histogram can be based on particular demands.
In this embodiment, multistage histogram has three levels 160,162,164.In this example, each level comprises 8 intervals (bin).First order Nogata Figure 160 is divided into 8 intervals with 256 luminance levels: each interval is corresponding to 32 luminance levels (256/8=32).Second level Nogata Figure 162 is corresponding between histogrammic two the best adjacent regions of the first order, and further corresponding 64 luminance levels is divided into 8 intervals (that is each interval 8 luminance level).Similarly, be divided into 8 intervals between two best adjacent regions of third level Nogata Figure 164 with second level Nogata Figure 162: each interval is corresponding to 2 luminance levels (16/8=2).This data decomposition betide change test 142 and threshold value determine 144 both.
Refer again to Fig. 6, determine in 144 in threshold value, image can be according to estimated time noise level and is analyzed.This is by assessment current environment and estimative: more specifically, by assessing various bright levels, the amount of bias light for example.In case the time noise level is appropriately determin, threshold value is determined just can be made, and wherein these data are sent to and change test 142.For per two successive frames, changing test can be performed at each picture element.This test can determine that 144 threshold value determines that the result compares with each image and previous image and from threshold value.Do not change if picture element is detected as with respect to former frame, then histogrammic respective bins can be increased 1.When the third level interval in the histogram reached its maximum height, corresponding picture element was marked as the processing that " will be registered " will be described in detail below carrying out.
Notice that under the situation with the ability of checking longer historical record rather than checking two frames simply, above-mentioned multistage histogram can provide a kind of method of saving memory to come nothing value of making an uproar of " the most static " pixel in the identification video.When picture element was marked as " will be registered ", data can be sent to benchmark registration 148.The value of respective pixel can be registered to reference buffer.Nogata Figure 160,162,164 interval are reset subsequently and whole process can be repeated.
Can use the reference buffer of any proper number.By using single buffer, the benchmark of being registered can systematically be replaced by newer value.Perhaps, by using a plurality of buffers, can be stored more than a benchmark.The newer value that is different from old value can be registered to new buffer.These values can be registered in 148 at benchmark and be determined, and are sent to video encoder 134a subsequently, and wherein these values are stored in the suitable memory location (for example benchmark 150) for using in skipping the coding decision process.
With reference now to Fig. 8,, Fig. 8 illustrates the rough schematic view that is used for making at the part of input video the exemplary decision tree 170 of skipping the coding decision.In this specific implementation mode, decision tree 170 shows the senior logical process that takes place in the coding module 136a of skipping at video encoder 134a.The senior coding module 136a that skips can receive data from three sources: from the prediction benchmark 172(of the video encoder 134a copy at preceding image after for coding), from the present image 174 of camera components 116 and from memory element (for example benchmark 150) skip benchmark 176, described memory element can comprise from the pixels of benchmark registration 148 registrations.Prediction benchmark 172 and present image 174 can be compared to produce frame difference 182.Present image 174 and skip benchmark 176 and can be compared to produce first reference differences 184.Predict benchmark 172 and skip benchmark 176 and can be compared to produce second reference differences 186.
When frame of video is encoded, skip benchmark 176 and can be used for helping to make to skip to encode determining.In this example, single reference buffer is used; Yet a plurality of reference buffer also can easily be used.In this embodiment of Fig. 8, when the nearest neighbours' of video blocks motion search being facilitated direct prediction (i.e. zero motion), video blocks is considered and skips coding.Under these circumstances, the metric of frame difference 182 is assessed at the threshold value of two strictnesses.Depend on noise level, be lower than low threshold value if these threshold values can be selected as making in judgement frame 188 place's frame difference metric values, then video blocks can be encoded as confident skipping.Perhaps, if be higher than big threshold value in judgement frame 190 place's frame difference metric values, then video blocks can be encoded as and confidently not skip.For those metrics between these values, the metric of reference differences 184 is further assessed at the present image 174 and judgement frame 192 places of skipping between the benchmark 176.Subsequently, this value can further be assessed at another threshold value that suitably defines in reference base picture (being used for inter prediction) and judgement frame 194 places of skipping between the benchmark 176.If for this twice comparison, all below threshold value, then video blocks is encoded as and skips the candidate metric.
With reference now to Fig. 9,, Fig. 9 is the simplified flow chart that illustrates a kind of possible operation that is associated with system 200.This flow process can start from step 210 place, and vision signal is captured as a series of images of displacement in time in this step.At step 212 place, raw image data can be sent to suitable video processing unit.Step 214 can comprise analyzes data to obtain changing statistics.At step 216 place, reference frame can be registered and store to be used for comparison subsequently.When Video Capture began, first image can form first reference frame.
Skipping coding determines the frame that can be made and do not skipped at step 218 place to be encoded at step 220 place.In step 222, new coded data can be sent to the second place via network with the data from the baseline encoded of being skipped part.These data are displayed on the display of the second place, as shown in step 224 as video image subsequently.In certain embodiments, similar process occurs in the second place (that is, counterparty's end points) and locates, and video data also is sent to primary importance from the second place in this case.
Then consider Video processing ability of the present disclosure on the other hand, facial detected activity, background/foreground optimization etc. can be implemented by architecture of the present disclosure.(note, the U.S. Patent application No.12/164 of " Combined Face Detection and Background Registration " (submission on June 30th, 2008) by name, 292 full content is included in the disclosure by reference at this.) in the stream video system such as video conference, video image can be regarded as the synthetic of background image and foreground image.Background image can comprise various stationary objects, and foreground image can comprise the object of motion.Especially in video conference, foreground image can refer to the people in the actual meeting, and background image can refer at the video image that does not have participant to be captured by camera under the situation of camera front.
According to some aspect of the present disclosure, the structure of background reference base picture can be based on change-detection.Under the situation of static background and substantially invariable illumination, change detection algorithm (for example being set in the encoder of given camera components) solves camera and quantizing noise.It is motion or static can being configured to test picture element (for example comprising pixel or small pixel piece) for the threshold technology of noise statistics data adaptive.This can be based on the difference between two successive frames.
More generally, example embodiment of the present disclosure can comprise and have dynamic inherent attribute the camera components 14,116,126 of (for example automatic exposure, Automatic white balance and focusing automatically) and external attribute (uncertain illumination etc.).In operation, camera components 14,116,126 performed methods can comprise to be analyzed camera output and identifies stationary part in the image according to temporal variation, and described temporal variation can be the transducer noise in time and the combination of variation that the adjustment of its inherent attribute (for example focus) is caused owing to camera.
These operations can also comprise utilizing exports the next static/senior coding of skipping of background area execution that imports frame into to being discerned.In addition, the operation that utilizes output to locate the contouring head (for example facial) in the foreground area of being told similarly can be performed.This method can be by handling the prospect be partitioned into or finishing from the texture of color space by the prospect that will tell and the combined or further combination of time difference (promptly moving) of frame and frame simply.This operation can also comprise by preferably bit being used in the facial zone of being located optimizes coding to foreground area.In different operating aspects, a kind of operation can be performed in camera components 14,116,126 with the measurement result of extracting output (face) and be used to emphasize from the quilt in those zones and carry out inherent adjusting.
Then consider and these movable relevant additional details, can be to the change-detection result of video data along time shaft by accumulative total.The histogram of average brightness value (Y) can be fabricated at each picture element in a plurality of picture elements.Histogrammic each interval can be corresponding to the level between 0 to 255.When the successive frame (L) for predetermined number, picture element all is identified as static, and then this picture element can be marked as static elements, and the interval that is associated in its histogram is increased 1 in the case.In addition, the colourity that is associated (U and V) value can quilt be average and storage at each is interval.This histogram building process can be repeated at each frame to carry out.In one embodiment, when an interval in its histogram reached predetermined value, picture element was registered in the background buffer.
Carried out background registration at the frame of predetermined number after, can be used to facial the detection to the initial registration of background.Background registration mask is held: the availability that indicates the background information of picture element.For each incoming frame, can produce differential image by subtracting background and then filtering noise from this frame.Under the situation that complete background picture can be used, perhaps under the situation that the unregistered part of background difference and image is coincide, draw the object mask according to the background difference image.Perhaps, the background difference image can make up with definite foreground object with frame difference and the background registration mask behind the noise filtering, and the formation object mask.In an example embodiment, the difference between present frame and former frame hour, nearest significant frame difference image is used.
In some exemplary implementation, the face that the object mask can be applied to complex background detects, will be confined to object mask (but not entire frame) based on the facial detected activity of edge and color.Complicated background can refer to have the background picture (for example comprising the texture with variable-brightness value) of inhomogeneous color, thereby produces a lot of edges when carrying out rim detection.Simple background refers to have the background of clear uniform texture and color: thus when carrying out rim detection, produce less edge result.
In an exemplary operations, detected head and trunk profile can be used in the background registration to regulate histogram.For example, when picture element was in detected face contour, it was 0 that the statistics of the respective bins in its histogram will be reset.In order to tackle noise, the statistics between adjacent region can be reduced to the fractional value of their preceding values: and the distance between they and actual zone is proportional.This method can be performed to reduce the mistake registration to static face and trunk data relevant with background.Perhaps, when picture element is not in detected profile, the part of the background that this picture element normally is not capped.By regulating histogram to reflect such possibility, the background that temporarily appears by moving face and trunk object can be registered fast.
Semantically, in order to make the static head of as a setting a part and the mistake registration of trunk are minimized, detected head and shoulder contour are fed to background registration (to regulate histogram).For example, if an element in detected profile, then to be reset be 0 to the respective bins in its histogram.In one embodiment, when the some parts of facial and torso area was registered as background a part of mistakenly, the background registration still can be used, up to utilizing the histogrammic new registration after regulating only to be available as.Perhaps, the background registration can be eliminated.In order to tackle noise, be reduced the fractional value of their preceding values between adjacent region: depend on their distances between actual zone, wherein said fractional value is followed for noise and is changed adaptive function.
With regard to concrete processing selecting, use multistage histogrammic algorithm can be utilized so that the memory utilization rate is reduced to approximately 1.5 bytes of each pixel from 256 bytes of each pixel through quantizing.Three grades of histograms can be fabricated at each piece of 4 * 4.In order to reduce the noise that is associated with background, the background registration can be at a period of time and processed, if wherein result and new value are all in threshold value, then result and new value is averaged.When average result and new value were not in threshold value, value before can replace new value.
In order to regulate histogram, when picture element is in facial and body contour, the statistics of its respective bins in first order histogram constant (but not increasing by 1).Subsequently, the statistics of its respective bins in the histogram of the second level can be halved, and its respective bins in third level histogram is eliminated.In addition, depend on that noise changes, histogrammic one or two the adjacent interval of the third level can be reduced to their 1/4th or half value.
In the operation of sample scenario, for each incoming frame, this architecture generates SOME RESULTS: the background picture after object (prospect) mask, head and trunk testing result and the renewal.Next two results can be fed back to encoder to improve the coding to subsequent frame.The face of this combination detects and the background enrollment has some benefits.The first, it has improved the face detection with complex background by being confined to the object mask based on the algorithm at color and edge.The second, it has improved background constructing by head and trunk are forced to non-background area, and this has been avoided those picture element mistakes are registered as background.
Background registration and the facial input that detects both can be primitive frames, and in this case, this architecture is independent of video encoder.The facial input that detects can be a primitive frame, and the input of background registration can be the output that rebuilds of video encoder.Encoder can utilize the result of facial detection and background registration to improve the facial zone coding of (with the background that is not capped).Background registration and the facial input that detects both can be the frames that rebuilds.This structure allows encoder to carry out the coding of the facial background that quantizes inclination and be not capped.Whole process can be replicated in encoder, and wherein decoder can synchronously make up and upgrade the background reference base picture with encoder, and this expense that can save bandwidth is to transmit constructed background picture.
The structure of background reference base picture can be based on change-detection.When static background and constant illumination were set, change detection algorithm (for example being located in camera components, the control desk element etc.) can solve camera and quantizing noise effectively.Can be used for the threshold technology of noise statistics data adaptive that to test picture element (pixel or small pixel piece) with the difference of utilizing two successive frames be motion or static.
Between the starting period, detection can start from the initial registration (after the frame operation background registration at some) to background, and described background has the unavailable background (promptly still unregistered) of certain part.Background registration mask can be held whether available with the background information of indication picture element.For each incoming frame, differential image is produced by subtracting background and then filtering noise from this frame.If complete background picture is available or the unregistered part of background difference and image is coincide, then can directly draw the object mask according to the background difference image.Otherwise the background difference image can make up to determine foreground object and formation object mask with (after also being noise filtering) frame difference and background registration mask.Under the insignificant situation of the difference between present frame and the former frame, nearest significant frame difference image can be used.At last, the object mask can be applied to facial the detection with the reply complex background, and this is by being confined to the object mask based on the face detection algorithm of edge and color but not entire frame realizes.
In the specific implementation mode, the face of combination detects and the background enrollment can be integrated in the video conference video encoder (for example described video encoder of Fig. 5).Facial testing result after the improvement and constructed background picture can be used in the various application, and for example facial background forecast that quantizes inclination and be not capped is as described in detail here.
